| 摘 要： | 丽长角巢蛾Xyrosaria lichneura在福建省泰宁县1 a发生5代,主要以幼虫危害雷公藤。10月中、下旬以蛹在寄主周围土壤中越冬,翌年3月下旬成虫开始羽化产卵。幼虫孵化后直接潜入雷公藤叶片内取食叶肉,仅留下叶的上表皮。幼虫4龄,1~4龄幼虫平均历期分别为2.93,3.24,4.52,5.33 d。7月第3代幼虫进入猖獗危害阶段。成虫产卵多在晚上进行,单雌产卵量约60粒。卵多散产在嫩叶背面主脉附近。 |

| Abstract: | Xyrosaria lichneuta Meyrick has 5 generations a year in Taining County,Fujian Province and attacks Tripterygium wilfordii mainly as larva.It overwinters as pupa in the soil around the host in the last twenty days of October.The adult emerges and lays eggs in late March the next year.After hat-ching,larva mines laminas directly and eats the mesophyll,leaving only the epicuticule.The larva has 4 instars and the average duration of the larvae in the 1st to 4th instars was about 2.93,3.24,4.52 and 5.33 days.The... |
